Accounts Receivables

Program

A complete menu-driven accounts receivable system packs date, customer name, and amount into fixed-width string records—with Shell sort, tape save, and optional printer output.

Card Trick

Program

This program implements the classic "21-card trick" in which a participant mentally selects one of 21 cards dealt face-up in three rows of seven.

Census

Program

Enter any date and watch this population clock estimate the U.S. population in real time, using an exponential growth formula with per-minute updates.

Drop Test

Program

Enter the seconds until you hear a dropped object hit the ground, and this physics program solves the quadratic equation to reveal the true drop height.

Pythagorean Triples

Program

A floating-point Pythagorean triple finder that uses clever epsilon-offset arithmetic to overcome rounding errors while scrolling results automatically on-screen.

Stumper

Program

A taunting number-battle game where you pick from ten skewed random values and the computer plays a greedy counter-strategy—can you outsmart "Stumper"?

Wind Chill

Program

Enter a temperature and wind speed to get the classic Siple-Passel wind chill index, with automatic restart after displaying the result.
